K15274 : TCP reassembly vulnerability CVE-2014-3000

Security Advisory Description

The TCP reassembly function in the inet module in FreeBSD 8.3 before p16, 8.4 before p9, 9.1 before p12, 9.2 before p5, and 10.0 before p2 allows remote attackers to cause a denial of service (undefined memory access and system crash) or possibly read system memory via multiple crafted packets, related to moving a reassemble queue entry to the segment list when the queue is full. (CVE-2014-3000)

Impact

An attacker who can send a series of specifically-crafted packets with a connection could cause a denial-of-service (DoS) situation, and although extremely difficult, may be able to obtain a portion of kernel memory.
